Notes:

1.Line and Load Regulation are measured at a constant junction temperature using a low duty cycle pulse technique. Although power dissipation is internally limited, regulation is guaranteed up to the maximum power dissipation of 60 W. Power dissipation is determined by the input/output differential voltage and the output current. Guaranteed maximum power dissipation will not be available over the full input/output voltage range.

3.32. Guaranteed by design, characterization or correlation to other tested parameters.

3.The • denotes the specifications which apply over the full operating temperature range.
